Application filed June 11, 1921. Serial No. 476,781.

T 0 all '10 ham it may concern Be it known'that l, JOSEPH H. Jones, a citizen'of the United States, residing at Tinthrop, in the county of Suffolk, State of ssach'usetts, have invented a certain new and useful IInprovement in Stop-lvlotion Mechanism for Spinning Frames, of which the following" is a specification, reference being had therein to the accompanying drawmgs.

"The invention is applicable to spinningframes and other machines in which yarns are wound upon bobbins or other receivers or carriers in weft-wound masses. Animportant application of the invention is in connection witha spinningtrame or the like of theTclass in which live caps are combined with and applied to tbeblades or barrels of riitatingspinning elementsf The invention"provides improved stopmotion mechanism designed "to unship the d'rit in"g power of 'amachine when tlieyarnmasses which are being wound upon the bobbins or other receivers therein have at tziinedthe predetermined length, to thereby discontinue theworking of the machine. It provides, further, stop motion mechanism by which, in thecase of a? spinning frame or the like of the class referred to, stopping is occasioned when the traverse brings about predetermined proximity of the caps to the tips of the blzidesoi barrels o f the rotating spinning elements, to safeguard thereby against disconnection and dislodgment of the caps from the spinning elements. Thereby I obviate the inconvenience ot'having the caps fall to the floor, and the breakage of the caps or iiriury'thereto which would "resalt from such falling.

Tl-1e invention consists, essentially, in fullboblliiii stop-motion mechanism comprising, in combination with a shipper anda shipperac tuator, a revoluble controller, tensioir meansiconnections combining said shipperaiituator, controller, andtension-means, a detent forsaid controller by'whichthe tensionmeans is held under restraint, and meansconnected with thetraverse mechan ism operating todisengage' the detent to free th'e'control'lerso as to permit actuation of the shipper actuatOr and shifting of the shipperbyftlie tension-means. It consists, further, in stop motion mechanism by which stopping is brouglitabout when the traverse brings aboutpredetermined proximity of the caps to the tips of the blades or barrels of the rotating spring elements.

The invention, in the preferred town of embodiment thereof, is illustrated in the drawings, in which 1a-tter,

' Fig. 1 is a partly sectional front elevation of portions of a cap-spinning,frame with the said embodiment applied thereto, the ma chine being represented in running condition.

Fig; 2 shows the same in vertical section in a plane parallel with theftront of the machine, on line 22 of Fig. 3, showing the driving belt shifted upon the loose pulley.

Fig. 3 is a view thereot'partly in horizoutal section on line 33 of Fig. I; also with the belt shifted upon the loose pulley.

The invention is applicable in connection with machines or frames ofvarious types. it is shown herein applied to a spinning- :frame in which the spinning is performed by means of spindles 1 mounted in bearings 2 carried by a spindle-rail 8, bobbins a mounted upon the said spindles, and live caps 5 mounted uponthe blades or barrels of the said bobbins and caused to revolve b frictional engagement with the said blades or'barrels. In the operation of such a spinning-frame the yarns which are in process of being spun extend down to and around the edges of the months at the lower ends of the caps 5 on their way to the bobbins, on which latter tley are wound to torn: the yarn-masses :r. The caps 5 are governed as to their position vertically through the peripheral engagement ot' their upwardly flaring bodies with supporting wheels or so-c-alled pivots (5 having their piniles fitted to bearings in supports 7 carried by a rail 8. The rail 8 is the traverserail in the case of this spinning-frame, it being given the usual movements required in the case of a tillingwind, namely a short rise and fallto distribute the yarns upon the bobbins in cone-shaped layers, and the usual gradual elevation to build theyarnmass progressively upward upon the bobbins by means of usual mechanism including vertical rods or pokers 9 supporting the rail 8 by'their upper ends, rockers l0, and traverse and builder-motion devices (not shown) connected with and actuating the rockers.

For the driving of the illustrated spinning-frame, its main shaft 11 is provided with a fixed or fast pulley 152 and loose pulley 13 to receive a driving-band 14,-, and

also is provided with a shipper 15 for said driving-band, the said shipper being carried by a shipper-rod l6 which in practice has combined therewith one or more operating handles (not shown) by means of which the shipper may be operated to shift the driving-band from the loose pulley to the fast pulley, or vice versa. 7

thus far described the parts, and the illustrated construction thereof, form no portion of the invention itself.

In carrying the invention into effect I provide a shipper-actuator, as a, and tension-means, as 7), for actuating the same, when required, to cause the shipper 15 to shift the driving-band 1-11; from fast pulley 12, (Fig. 11) over on to the loose pulley 13, (Figs. 2 and 3). These may be varied in character, etc, more or less in practice. In this instance the sl1ipperactuator is a bar that is disposed between the shipper and the adjacent end-portion 17 of the machinefraine and is adapted to engage the hub by means of which the shipper is mounted upon shipper-rod 16. The said rod passes freely through a hole in the said bar. The bar is fixed upon the outer ends of two rods 0, a, which are fiitted to guide-bean ings a a in said end-portion 17, with capacity to slide endwise therein. The tensionmeans in this instance comprises two weights b 7), which are combined with the shipperactuator by flexible connections, in this instance chains 0, 0, that are so conducted and connected with the inner ends of rods a. a. that the force due to the gravitatingtendency of the weights acts in the direction to carry the shipper and driving-band over from the fast pulley to the loose pulley. Herein the chains pass upward from the weights to and partly around sprocket-wheels (.Z, (Z, forming part of the revoluble controller for the shil'iper-actiiator, and from the said sprocket-wheels the chains extend substantially horizontally to their points of connection 6, 6, with the inner ends of the rods a, a.

The revoluble controller for the shipperactuator comprises the sprocket-wheels (Z, (Z, a shaft d" on which said sprocket-wheels are fixed, and a detent-wheel or collar (Z on the front end of s iaft d, the said detent-wheel or collar having one or more, usually one, tooth or teeth (i At f is the detent by means of which the revoluble controller is held from turning, so that by reason thereof and of the engage ment of the teeth of the sprocket-wheels d, d. with the links of the chains 0, c, the tension-means is held in restraint, and prevented from producing movement of the shi iper-actuator and shipper, in the direction to carry the'driving-band from thcfast pulley over to the loose pulley. The detent in this instance is a dog or pawl which is hinged at f upon a convenient support and furnished with a tooth for engagement with the tooth (Z of the detent-wheel or with one of the teeth thereof in case the detent-wheel should have more than one. ment of the shipper-actuator with relation to the shipper is such, as shown by the drawings, that when shipper-rod 16 is moved toward the left in the drawing-s for the purpose of shifting the driving-band over from the loose pulley to the fast pulley (Fig. 1), in order tostart up the machine, the shipperactuator is pushed inward into its idle position, raising the weights and turning the controller until the tooth (Z is carried around past the tooth of detent f and the detent enters into engagement with such tooth, thereby locking the shipper-actuator in the said idle position, as shown in Fig. 1. So long as such engagement .continues the shipper-actuator remains in the idle position, free from the pull of the tension-means. While the shipper-actuator occupies its idle position, the shipper is free to be operated by hand for the purpose of stopping and starting the machine from time to time as may be required.

Inthis instance, for the automatic disengagement of the detent f'and release of the revoluble controllerv when the winding-on 0f the yarn has arrived at the predetermined limit and thereby brought about the predetermined proximity of the caps to the tips of the bobbins, a part or member 9 having an adjustable stop or collar 9 thereon is connected pivotally at g with detent A second member, [1-, in sliding engagement with member 9, and adapted for engagement with said stop or collar. is connected with the traverse mechanism so as to be recipro cated upon member y in unison with the traverses of thetraverse-rail, and also so as to progressively approach the stop or collar g as the traverse-rail shifts progressively in the direction of the length of the bobbins. Member g is a screw-threadedrod. The ad justable stop or collar 9' is. a nut and checlo nut upon said rod. and mounted upon the rod with capacity to slide endwise thereon. The connection between member 71. and the traverse mechanism in this-instance is by means of a bell-crank i that is mounted pivotally at 11 upon the machine-frame, and a link is. One arm of the bell-crank is engaged with a pivot 71 projecting from a collar 2' secured upon tubula member A by means of a clamping screw it. The other arm of the bell-crank has con nected pivotally thereto one end of link is, the other end of the latter being connected pivot-ally to the rod or connector 10* which The arrange- I Member it is tubular connects together the rockers 10 of the traverse-mechanism. Through these connections the tubular member 71- is caused to reciprocate endwise upon member 9 in unison with the up and down movements of the traverse-rail in distributing the short conical layers of yarn upon the yarn-masses it upon the bobbins, and also to gradually approach the stop or collar 9 as the progressive shift of the traverse-rail lengthwise of the bobbins takes place. lVhen, finally, such progressive shift has brought the caps and the winding to the predetermined closeness to the tips of the bobbins, the gradual approach of the upper end of tubular member it to the stop g brings about in one 'of the short traverses to the nose of the tapering filling-mass engagement of such end with the said stop and thereby disengages the detent 7 from the tooth of the detent-wheel (Z thereby freeing the rev oluble controller and permitting the tension-means to actuate the shipper-actuator and shipper to ship the driving-band over upon the loose pulley and thus bring about stoppage of the working of the machine.

Through adjustment of the stop 9' upon member g, or of member h in connection with collar i the stoppage may be caused to take place when the winding arrives at any predetermined point in the lengths of the bobbins.

In practice, the construction and arrangeu'ient of the parts may vary more or less,

according as preferred or as made necessary by specific differences in the build, arrangement and mode of operation of the spinning frames and of other machines with which the features of the invention are combined.
